1. GENERAL INFORMATION

1-1. Inroduction and description

This manual describes the installation, operation, and maintenance of the HF+6m solid-state linear power amplifier ACOM 700S.

ACOM 700S is a state-of-the art linear amplifier, covering the amateur bands from 1.8 to 54MHz with 700W output power (PEP or continuous carrier) with less than 40W of drive. The amplifier operating information is shown on a multi-functional, high resolution color display. ACOM 700S may by controlled either by the six front panel buttons or remotely – via an RS232 port.

NOTE

ACOM 700S is designed to work with the ACOM 04AT Remote Automatic Antenna Tuner. The connection of ACOM04AT will make accessible the features that are inactive onthe amplifier display when ACOM 700S operates without

ACOM 04AT. The operation of ACOM 700S with ACOM 04AT is described in the ACOM 04AT Operation Manual.

1-2. Owner assistance

If technical or operating assistance is needed, please contact your local dealer first. In the unlikely case of you needing further information, you may get in touch with ACOM via: fax (+ 359 2 920 96 56), telephone [phone]), e-mail ([e-mail], [e-mail]) or by post (blvd.

Nikola Mushanov 151, 1330 Sofia, Bulgaria). Website: www.acom-bg.com.

1-3. Equipment supplied and options

The amplifier is supplied in a single box including:

-amplifier ACOM 700S;

-power cord;

-this manual with a CE declaration of compliance;

-four pieces of spare fuses

1-4. Features

•5“ high resolution color display (108x65mm), 800x480 pixels, and 24-bit color.

•The final PA stage uses a rugged LDMOS transistor - BLF188XR.

•Compatible with all transceiver models available on the market - does not need any special signals: „ground on transmit“ and less than 40W of RF drive power is sufficient.

•Broadband input circuit, providing a perfect transceiver load with SWR below 1.2:1 (typically 1.1:1), without retuning throughout the whole frequency range from 1.8 to 54MHz.

•The overall operation of ACOM 700S is extremely simplified : the screen menus are intuitive and easy to follow, no special skill is required from the operator when changing frequency bands.
